Prepare to cringe as you see this marathon runners d*ck fall out mid race

Imagine the worst ever thing that could happen to you, times it by 1 million and then you'll get to the level of the absolute nightmare that has happened to this lad.

Poor Jozef Urban was running a marathon (which is punishment enough) and was nearing the end of the race when his genitalia popped out; whether Urban was aware that he was suddenly on a nudie run isn't clear but he finished regardless, coming in a respectable tenth place.

He also somehow managed to shave 27 seconds off his personal best, maybe running in humiliation is the secret? 

Watch the mortifying vid above!
